I've not validated these work.

If the variable has not been set the "." notation will throw an exception. So typically _always_ use flowVars['outboundJmsQueue']
<when expression="org.mule.util.StringUtils.isNotEmpty(sessionVars['outboundJmsQueue'])">
    <!-- It is set, so do something -->
</when>

<when expression="org.mule.util.StringUtils.isNotEmpty(flowVars['outboundJmsQueue'])">
    <!-- It is set, so do something -->
</when>
